Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in a wooden column-beam structure with a high floor height (ceiling height), buckling of the wooden column supporting the wooden beam becomes a problem.

[0006] As a countermeasure, for example, it is conceivable to increase the cross-sectional area of the wooden column. However, in this case, it takes time and effort for the production, transportation, and hoisting of the wooden column.

[0007] In consideration of the above facts, an object of the present invention is to suppress buckling of a wooden column while suppressing an increase in the cross-sectional area of the wooden column in a wooden column-beam structure.

Means for Solving the Problems

[0008] The wooden column-beam structure according to claim 1 comprises a built-up column having a wooden beam, an outer wooden column that supports one end side of the wooden beam in the span direction, a pair of inner wooden columns that are arranged closer to the center side of the wooden beam in the span direction than the outer wooden column and that support the wooden beam while sandwiching it from both sides in the beam width direction, and a connecting beam that connects the intermediate portions in the material axis direction of the outer wooden column and the pair of inner wooden columns.

[0009] According to the wooden column-beam structure according to claim 1, the built-up column has an outer wooden column, a pair of inner wooden columns, and a connecting beam. The outer wooden column supports one end side of the wooden beam in the span direction. A pair of inner wooden columns are arranged closer to the center side of the wooden beam in the span direction than this outer wooden column. The pair of inner wooden columns support the wooden beam while sandwiching it from both sides in the beam width direction. Further, the intermediate portions in the material axis direction of the outer wooden column and the pair of inner wooden columns are connected by the connecting beam. Thereby, the built-up column is constituted.

[0010] By configuring the built-up column in this way, it is possible to suppress buckling of the outer wooden column and the pair of inner wooden columns while suppressing an increase in the cross-sectional area of the outer wooden column and the pair of inner wooden columns. Therefore, a wooden column-beam structure with a high floor height (ceiling height) can be realized.

[0011] Also, by providing two (a pair) of inner wooden columns with a larger axial force than the outer wooden column, it is possible to configure a reasonable wooden column-beam structure while suppressing an increase in the cross-sectional area of the pair of inner wooden columns.

[0012] Furthermore, by supporting the wooden beam while sandwiching it from both sides in the beam width direction by the pair of inner wooden columns, the joining structure between the pair of inner wooden columns and the wooden beam can be simplified.

[0013] The wooden column-beam structure according to claim 2 is the wooden column-beam structure according to claim 1, and further comprises a diagonal member provided in a framed portion surrounded by the wooden beam, the outer wooden column, the pair of inner wooden columns, and the connecting beam. The outer wooden column and the pair of inner wooden columns each have a pin-jointed column joint at the intermediate portion.

[0014] According to the wooden column-beam structure according to claim 2, a diagonal member is provided in a frame-shaped portion surrounded by a wooden beam, an outer wooden column, a pair of inner wooden columns, and a connecting beam. Further, the outer wooden column and the pair of inner wooden columns each have a pin-jointed column joint at an intermediate portion in the direction of the material axis.

[0015] Here, by providing a diagonal member in the frame-shaped portion, a truss can be formed. Thereby, the column joints at the intermediate portions in the direction of the material axis in the outer wooden column and the pair of inner wooden columns can be reasonably pin-jointed. Therefore, the workability of the column joints of the outer wooden column and the pair of inner wooden columns is improved.

[0016] The wooden column-beam structure according to claim 3 is the wooden column-beam structure according to claim 1, further comprising a plurality of said built-up columns provided in a direction orthogonal to the span direction of the wooden beam, an outer orthogonal connecting beam connecting the intermediate portions of the adjacent outer wooden columns in the orthogonal direction, and an inner orthogonal connecting beam connecting the intermediate portions of the adjacent inner wooden columns in the orthogonal direction.

[0017] According to the wooden column-beam structure according to claim 3, a plurality of built-up columns are provided in a direction orthogonal to the span direction of the wooden beam. And the intermediate portions of the adjacent outer wooden columns in the orthogonal direction are connected by an outer orthogonal connecting beam. Also, the intermediate portions of the adjacent inner wooden columns in the orthogonal direction are connected by an inner orthogonal connecting beam. Thereby, buckling of the outer wooden column and the inner wooden column in the orthogonal direction is suppressed.

[0018] The wooden column-beam structure according to claim 4 is the wooden column-beam structure according to any one of claims 1 to 3, wherein the wooden beam is pin-jointed to the outer wooden column and is also pin-jointed to the pair of inner wooden columns.

[0019] According to the wooden column-beam structure according to claim 4, the wooden beam is pin-jointed to the outer wooden column and is also pin-jointed to the pair of inner wooden columns. Thereby, the workability of the joint portions between the wooden beam, the outer wooden column, and the pair of inner wooden columns is improved.

Advantages of the Invention

[0020] As described above, according to the present invention, in a wooden column-beam structure, it is possible to suppress buckling of the wooden column while suppressing an increase in the cross-sectional area of the wooden column.

Mode for Carrying Out the Invention

[0022] Hereinafter, an embodiment will be described with reference to the drawings.

[0023] (Structure) In FIG. 1, a structure 10 according to the present embodiment is shown. As an example, the structure 10 is a large-space structure with a high floor height (ceiling height) such as a gymnasium, an exhibition hall, or a hall, and has a large space 12 inside. This structure 10 includes a plurality of wooden column-beam structures 20.

[0024] Note that the arrow X direction appropriately shown in each figure indicates the long span direction of the structure 10 (long span direction), and the arrow Y direction indicates the short span direction of the structure 10 (short span direction).

[0025] (Wooden column and beam structure) The plurality of wooden column and beam structures 20 are long span structures (large span structures). These wooden column and beam structures 20 are arranged along the long span direction (arrow X direction) of the structure 10 and are spaced apart in the short span direction (arrow Y direction) of the structure 10 as shown in FIGS. 2 and 3. Further, the plurality of wooden column and beam structures 20 constitute a roof structure.

[0026] The wooden column and beam structure 20 is formed, as an example, by combining standard-sized woods (standard members). This wooden column and beam structure 20 has a wooden beam 30, a timber 36, a bundled material 38, and a pair of combined columns 40.

[0027] (Wooden beam) The wooden beam 30 is formed in a rectangular cross-sectional shape and, as an example, constitutes a roof beam of a gable roof. Also, the wooden beam 30 is arranged along the long span direction in plan view. In other words, the wooden beam 30 is arranged with the span direction as the long span direction. This wooden beam 30 has a pair of inclined beams 32 that constitute the roof beam. Note that the pair of inclined beams 32 is an example of beam members.

[0028] The pair of inclined beams 32 incline downward from the center in the span direction of the wooden beam 30 toward the combined column 40. The pair of inclined beams 32 are joined (semi-rigidly joined) at the top 30T of the wooden beam 30 such that the respective one ends (upper ends) are convex upward when viewed from the out-of-plane direction (arrow Y direction) of the wooden column and beam structure 20.

[0029] Each inclined beam 32 has a pinned beam joint. Specifically, each inclined beam 32 has two pieces of wood 32E of the same cross-section. The two pieces of wood 32E are arranged in the span direction of each, and are pinned together with their one ends butted against each other. More specifically, as shown in FIGS. 4 and 5, the two pieces of wood 32E are pinned together by the GIR (Glued-in Rod) method using rods 34 and an adhesive.

[0030] Note that the two pieces of wood 32E are not limited to the GIR method, and may be joined by a metalworking method such as a steel plate inserted drift pin joint method, for example.

[0031] (Timber) As shown in FIG. 1, a pair of inclined beams 32 are connected by a timber 36. The timber 36 is a tension member that handles the thrust force generated in the pair of inclined beams 32. Also, the timber 36 is formed of wood and is arranged along the span direction of the wooden beam 30 below the wooden beam 30.

[0032] Both ends of the timber 36 are joined (pinned) to the pair of inclined beams 32 on the center side in the span direction of the wooden beam 30 rather than the built-up column 40 described later.

[0033] (Built-up member) The central part in the material axis direction of the timber 36 and the top 30T of the wooden beam 30 are connected by a built-up member (built-up column) 38. The built-up member 38 is formed of wood and is arranged along the vertical direction.

[0034] The upper end of the built-up member 38 is joined (pinned) to the top 30T of the wooden beam 30, and its lower end is joined (pinned) to the central part in the material axis direction of the timber 36. A truss is constituted by these wooden beam 30, timber 36, and built-up member 38.

[0035] Note that the timber 36 and the built-up member 38 may be provided as necessary and can be omitted as appropriate.

[0036] (Built-up column) A pair of built-up columns 40 are arranged on both sides of the wooden column-beam structure 20. Also, the pair of built-up columns 40 are erected on the foundation 14. Each built-up column 40 has an outer wooden column 50, a pair of inner wooden columns 60, a connecting beam 70, and a diagonal member 82.

[0037] (Outer wooden column) As shown in FIGS. 6 and 7, the outer wooden column 50 is formed in a prismatic shape and supports one end side in the span direction of the wooden beam 30. Specifically, at the upper end of the outer wooden column 50, the other end (lower end) of the inclined beam 32 of the wooden beam 30 is pin-jointed by a metalworking method using a connecting metal 52 and bolts 54.

[0038] As shown in FIGS. 8 and 9, the outer wooden column 50 has a pin-jointed column joint 50J at the middle part in the material axis direction. Specifically, the outer wooden column 50 has two pieces of wood 50E. The two pieces of wood 50E are arranged in the span direction of each. Also, the two pieces of wood 50E are pin-jointed in a state where one end portions are abutted against each other at the middle part in the material axis direction of the outer wooden column 50.

[0039] The two pieces of wood 50E are pin-jointed by, for example, a GIR method using a rod 56 and an adhesive. A pair of inner wooden columns 60 are arranged on the center side in the span direction of the wooden beam 30 with respect to this outer wooden column 50.

[0040] Note that the two pieces of wood 50E are not limited to the GIR method and may be joined by a metalworking method such as a steel plate insertion drift pin joint method, for example. Also, the middle part in the material axis direction of the outer wooden column 50 means the central part when the outer wooden column 50 is trisected in the material axis direction.

[0041] (Inner wooden column) The pair of inner wooden columns 60 are formed in a prismatic shape and support the wooden beam 30 by sandwiching it from both sides in the beam width direction. Specifically, as shown in FIGS. 4 and 5, the pair of inner wooden columns 60 are arranged on both sides of the wooden beam 30 in the beam width direction. The upper end portions of the pair of inner wooden columns 60 and the wooden beam 30 are pin-jointed by through bolts 62 penetrating in the beam width direction of the wooden beam 30.

[0042] Note that the upper end portions of the pair of inner wooden columns 60 and the wooden beam 30 may be joined not only by the through bolts 62 but also by methods such as the GIR method or the hardware method. Also, the intermediate portion in the material axis direction of the inner wooden column 60 means the central portion when the inner wooden column 60 is trisected in the material axis direction.

[0043] As shown in FIGS. 8 and 9, each inner wooden column 60 has a pin-jointed column joint 60J at the intermediate portion in the material axis direction. Specifically, the inner wooden column 60 has two pieces of wood 60E. The two pieces of wood 60E have the same cross-section as the two pieces of wood 50E that make up the outer wooden column 50.

[0044] The two pieces of wood 60E are arranged in their respective material axis directions and are joined in a state where their one end portions abut against each other at the intermediate portion in the material axis direction of the inner wooden column 60. These two pieces of wood 60E are pin-jointed by, for example, the GIR method using a rod 64 and an adhesive.

[0045] Note that the two pieces of wood 60E may be joined not only by the GIR method but also by hardware methods such as the steel plate inserted drift pin joint method.

[0046] (Connecting beam) The intermediate portions in the material axis directions of the outer wooden column 50 and the pair of inner wooden columns 60 are connected by a connecting beam 70. The connecting beam 70 is formed in a rectangular cross-sectional shape and is arranged along the span direction of the wooden beam 30.

[0047] One end of the connecting beam 70 in the span direction is pinned to the middle part in the material axis direction of the outer wooden column 50 by a joining metalworking method using a bracket 72 and bolts 74.

[0048] The other end of the connecting beam 70 in the span direction is arranged between the middle parts in the material axis direction of the pair of inner wooden columns 60. In other words, the other end of the connecting beam 70 is sandwiched by the middle parts in the material axis direction of the pair of inner wooden columns 60 from both sides in the beam width direction. The other end of these connecting beams 70 and the middle parts of the pair of inner wooden columns 60 are pinned together by through bolts 76 passing through the connecting beam 70 in the beam width direction.

[0049] In this embodiment, due to fitting relationships and the like, the connecting beam 70 is joined to the outer wooden column 50 and the pair of inner wooden columns 60 below the column joints 50J and 60J of the outer wooden column 50 and the pair of inner wooden columns 60. However, the connecting beam 70 may be joined to the outer wooden column 50 and the pair of inner wooden columns 60 above the column joints 50J and 60J of the outer wooden column 50 and the pair of inner wooden columns 60.

[0050] Here, the built-up column 40 is formed by connecting the middle parts in the material axis direction of the outer wooden column 50 and the pair of inner wooden columns 60 with the connecting beam 70. Also, by connecting the middle parts in the material axis direction of the outer wooden column 50 and the pair of inner wooden columns 60 with the connecting beam 70, the buckling lengths of the outer wooden column 50 and the pair of inner wooden columns 60 are shortened.

[0051] (Diagonal member) A frame portion 80 is formed by the wooden beam 30, the outer wooden column 50, the pair of inner wooden columns 60, and the connecting beam 70. Inside this frame portion 80, diagonal members 82 are provided. The diagonal members (braces) 82 are arranged around the diagonals of the frame portion 80, and their upper ends are joined (pinned) to the wooden beam 30 via rods 84 (see FIG. 6), and their lower ends are joined (pinned) to the connecting beam 70 via rods 86 (see FIG. 8).

[0052] Here, the diagonal member 82 and the frame-shaped portion 80 constitute a truss. As a result, the column joints 50J and 60J of the outer wooden column 50 and the pair of inner wooden columns 60 are rationally pin-joined.

[0053] (Outer orthogonal connecting beam) As shown in FIG. 2, the plurality of built-up columns 40 are arranged at intervals in the orthogonal direction (arrow Y direction, short span direction) orthogonal to the span direction of the wooden beam 30. The intermediate portions in the material axis direction of adjacent outer wooden columns 50 are connected by an outer orthogonal connecting beam 90. The outer orthogonal connecting beam 90 is formed of a wood having a rectangular cross section. The outer orthogonal connecting beam 90 shortens the buckling length of the outer wooden column 50 in the orthogonal direction.

[0054] Note that the upper end portions of adjacent outer wooden columns 50 are connected by a connecting beam 92.

[0055] (Inner orthogonal connecting beam) As shown in FIG. 3, the intermediate portions in the material axis direction of the inner wooden columns 60 in the adjacent built-up columns 40 in the above orthogonal direction (arrow Y direction) are connected by an inner orthogonal connecting beam 100. The inner orthogonal connecting beam 100 is formed of a wood having a rectangular cross section. The inner orthogonal connecting beam 100 shortens the buckling length of the inner wooden column 60 in the orthogonal direction.

[0056] Note that the upper end portions of adjacent inner wooden columns 60 are connected by a connecting beam 102. Further, the top portions 30T of adjacent wooden beams 30 are connected by a connecting beam 104.

[0057] (Function) Next, the function of the present embodiment will be described.

[0058] As shown in FIG. 1, the built-up column 40 includes an outer wooden column 50, a pair of inner wooden columns 60, and a connecting beam 70. The outer wooden column 50 supports one end side in the span direction of the wooden beam 30. A pair of inner wooden columns 60 are arranged on the center side in the span direction of the wooden beam 30 rather than the outer wooden column 50.

[0059] A pair of inner wooden columns 60 support the wooden beam 30 by sandwiching it from both sides in the beam width direction. Further, the intermediate portions in the material axis direction of the outer wooden column 50 and the pair of inner wooden columns 60 are connected by a connecting beam 70. Thereby, the built-up column 40 is formed.

[0060] By forming the built-up column 40 in this way, it is possible to suppress buckling of the outer wooden column 50 and the pair of inner wooden columns 60 while suppressing an increase in the cross-sectional area of the outer wooden column 50 and the pair of inner wooden columns 60. Therefore, a wooden column-beam structure 20 with a high story height can be realized.

[0061] Further, by supporting one end side in the span direction of the wooden beam 30 by the outer wooden column 50 and the pair of inner wooden columns 60, the joints between the outer wooden column 50 and the pair of inner wooden columns 60 and the wooden beam 30 can be made pin joints respectively. Also, since the wooden beam 30 becomes a Gerber beam, a continuous beam effect can be obtained.

[0062] Furthermore, by using two (a pair) of inner wooden columns 60 with a larger axial force than the outer wooden column 50, a reasonable wooden column-beam structure 20 can be configured while suppressing an increase in the cross-sectional area of the pair of inner wooden columns 60.

[0063] Furthermore, in this embodiment, small-section standard-sized lumber (standard members) can be used for the outer wooden column 50 and the pair of inner wooden columns 60. Therefore, the transportability, hoisting property, and constructability of the outer wooden column 50 and the pair of inner wooden columns 60 are improved, and the cost can be reduced.

[0064] Also, by supporting the wooden beam 30 by sandwiching it from both sides in the beam width direction by the pair of inner wooden columns 60, the joint structure between the pair of inner wooden columns 60 and the wooden beam 30 can be simplified. In other words, the pair of inner wooden columns 60 and the wooden beam 30 can be easily joined by through bolts 76.

[0065] Furthermore, a diagonal member 82 is provided in a frame-shaped portion 80 surrounded by a wooden beam 30, an outer wooden column 50, a pair of inner wooden columns 60, and a connecting beam 70. Also, the outer wooden column 50 and the pair of inner wooden columns 60 each have pin-jointed column joints 50J and 60J at intermediate portions in the direction of the material axis.

[0066] Here, by providing the diagonal member 82 in the frame-shaped portion 80, a truss can be formed. As a result, the column joints 50J and 60J at the intermediate portions in the direction of the material axis of the outer wooden column 50 and the pair of inner wooden columns 60 can be reasonably pin-jointed. Therefore, the workability of the column joints 60J of the outer wooden column 50 and the pair of inner wooden columns 60 is improved.

[0067] Also, a plurality of built-up columns 40 are provided in a direction orthogonal to the span direction of the wooden beam 30 (the direction of arrow Y). The intermediate portions of the outer wooden columns 50 adjacent to each other in the orthogonal direction are connected by an outer orthogonal connecting beam 90. The intermediate portions of the inner wooden columns 60 adjacent to each other in the orthogonal direction are connected by an inner orthogonal connecting beam 100. Thereby, buckling of the outer wooden column 50 and the inner wooden column 60 in the orthogonal direction is suppressed.

[0068] Furthermore, the wooden beam 30 is pin-jointed to the outer wooden column 50 and is also pin-jointed to the pair of inner wooden columns 60. Thereby, the workability of the joint portions between the wooden beam 30, the outer wooden column 50, and the pair of inner wooden columns 60 is improved.

[0069] (Modification example) Next, a modification example of the above-described embodiment will be described.

[0070] In the modification example shown in FIG. 10, a wall-shaped connecting plate 110 is provided on the inner wooden column 60. The wall-shaped connecting plate 110 is formed of, for example, structural plywood or the like. This wall-shaped connecting plate 110 is arranged across the inner wooden columns 60 of the built-up columns 40 adjacent to each other in the orthogonal direction and connects these inner wooden columns 60. By this wall-shaped connecting plate 110, buckling of the inner wooden column 60 in the orthogonal direction can be suppressed.

[0071] In the modification shown in FIG. 10, a floor-like connecting plate 112 is provided on the connecting beams 70 adjacent to each other in the orthogonal direction. For example, it is formed of structural plywood or the like. This floor-like connecting plate 112 is arranged across the connecting beams 70 of the built-up columns 40 adjacent to each other in the orthogonal direction, and connects these connecting beams 70. By this floor-like connecting plate 112, buckling in the orthogonal direction of the outer wooden column 50 and the inner wooden column 60 can be suppressed.

[0072] In the above-described embodiment, the intermediate portions in the material axis direction of the outer wooden columns 50 adjacent to each other in the orthogonal direction (arrow Y direction, short span direction) orthogonal to the span direction (arrow X direction) of the wooden beam 30 are connected by the outer orthogonal connecting beam 90. However, the outer orthogonal connecting beam 90 may be provided as necessary and can be appropriately omitted.

[0073] Similarly, in the above-described embodiment, the intermediate portions in the material axis direction of the inner wooden columns 60 in the built-up columns 40 adjacent to each other in the above-described orthogonal direction (arrow Y direction) are connected by the inner orthogonal connecting beam 100. However, the inner orthogonal connecting beam 100 may be provided as necessary and can be appropriately omitted.

[0074] In the above-described embodiment, the column joints 50J and 60J at the intermediate portions in the material axis direction of the outer wooden column 50 and the pair of inner wooden columns 60 are pin-jointed. However, the column joints 50J and 60J are not limited to pin-joints, and may be semi-rigid joints or the like. Also, the outer wooden column 50 can be formed of at least one piece of wood 50E. Similarly, the inner wooden column 60 can be formed of at least one piece of wood 60E.

[0075] In the above-described embodiment, the beam joint of the inclined beam 32 is pin-jointed. However, the beam joint of the inclined beam 32 is not limited to pin-joints, and may be semi-rigid joints or the like. Also, the inclined beam 32 can be formed of at least one piece of wood 32E.

[0076] In the above-described embodiment, the outer wooden column 50, the pair of inner wooden columns 60, and the wooden beam 30 are pin-jointed. However, the outer wooden column 50, the pair of inner wooden columns 60, and the wooden beam 30 are not limited to pin-joints and may be semi-rigid joints or the like.

[0077] In the above-described embodiment, the wooden column-beam structure 20 is formed by combining standard-sized lumber (standard members). However, the wooden column-beam structure 20 is not limited to standard-sized lumber and may be formed by combining non-standard lumber.

[0078] In the above-described embodiment, the cross-sections (cross-sectional shapes and cross-sectional areas) of the outer wooden column 50 and the pair of inner wooden columns 60 are the same. However, the cross-sections of the outer wooden column 50 and the pair of inner wooden columns 60 are not limited to being the same and may be different.

[0079] In the above-described embodiment, the wooden beam 30 constitutes the roof beam of a gabled roof. However, the wooden beam 30 is not limited to a gabled roof and may constitute, for example, the roof beam of a mono-pitched roof or a hipped roof. Also, the wooden beam 30 is not limited to a roof beam and may constitute, for example, a beam that supports a floor on an intermediate floor of a structure.

[0080] In the above-described embodiment, a pair of built-up columns 40 are provided in the wooden column-beam structure 20. However, at least one of the pair of columns constituting the wooden column-beam structure can be the built-up column 40 according to the above-described embodiment.

[0081] In the above-described embodiment, a plurality of wooden column-beam structures 20 are provided in a direction orthogonal (arrow Y direction) to the span direction (arrow X direction) of the wooden beam 30. However, at least one wooden column-beam structure 20 can be provided in the structure 10.

[0082] In the above-described embodiment, the structure 10 is a large-space structure. However, the structure 10 is not limited to a large-space structure and may be other structures.

[0083] As described above, although one embodiment of the present invention has been described, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be used in appropriate combination, and of course, the present invention can be implemented in various modes without departing from the gist of the present invention.
